| abstractText | A novel human gene RED, and the murine homologue, MuRED, were cloned. These genes were named after the extensive stretch of alternating arginine (R) and glutamic acid (E) or aspartic acid (D) residues that they contain. We term this the 'RED' repeat. The genes of both species were expressed in a wide range of tissues and we have mapped the human gene to chromosome 5q22-24. MuRED and RED shared 98% sequence identity at the amino acid level. The open reading frame of both genes encodes a 557 amino acid protein. RED fused to a fluorescent tag was expressed in nuclei of transfected cells and localised to nuclear dots. Co- localisation studies showed that these nuclear dots did not contain either PML or Coilin, which are commonly found in the POD or coiled body nuclear compartments. Deletion of the amino terminal 265 amino acids resulted in a failure to sort efficiently to the nucleus, though nuclear dots were formed. Deletion of a further 50 amino acids from the amino terminus generates a protein that can sort to the nucleus but is unable to generate nuclear dots. Neither construct localised to the nucleolus. The characteristics of RED and its nuclear localisation implicate it as a regulatory protein, possibly involved in transcription. |
